'DataSHIELD' is an infrastructure and series of R packages that
enables the remote and 'non-disclosive' analysis of sensitive research data.
This package is the 'DataSHIELD' interface implementation for 'Opal', which is
the data integration application for biobanks by 'OBiBa'. Participant data, once
collected from any data source, must be integrated and stored in a central
data repository under a uniform model. 'Opal' is such a central repository.
It can import, process, validate, query, analyze, report, and export data.
'Opal' is the reference implementation of the 'DataSHIELD' infrastructure.
